#160 of 194 2004 Chevy Malibu Starting problems
Dec 12, 2009 (1:42 pm)
We have a 2004 Chevy Malibu LT. For some reason, randomly the car does not start. We are wondering if its the battery but I doubt this since the car starts on other occasions. Also when the car doesn't start, the radio, turn signals and dash all light up and work.
The only way to start to car is to give it a boost. Besides the battery needing to be replaced has anyone else heard or experienced this problem before? We are also suddenly having problems with the remote starter. When we try to remote start, the light just flashes and the starter gives up.

Check TPS for smooth and linear electrical response over the entire range of motion. If not, replace.
No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmision is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the underhood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.
EPC (Electronic Pressure Control) solenoid failed. Easy fix in pan. Fix as soon as possible or hard parts will eventually break.Broken spring(accumulator)
Just some things to look at !

We are having a problem with our horn. When we honk, the noise is not clear, it almost sounds as if the horn is worn out. Anyone know if this can be replaced?

Yes, I had the same issue, I had to have the key ignition replace. The key was not making contact, and this would cause my anti-system to shut down. Once I have the Ignition replace the problem stop.
The problem that I am experiencing now is with my car is not getting gas. I've had the fuel pump replace three times, and I am still experiencing the same issue. Hope you can advise.

My car just did this same exact thing to me...except its not starting at all now. Calling the dealership to come get it and check it out. I know its time for a tune up but to stop starting all together...just hoping its not too expensive this go around. I will post again once I know the outcome.
#166 of 194 PASSLOCK SECURITY system FIXED
Oct 02, 2010 (9:35 am)
For those of you who have a 1997 - 2003 Malibu and have been having problems with the Security system keeping you from starting the car, read on....
I am a retired GM Electrical Engineer. I own a 2002 Grand Am, and had this problem two years ago. I bought a Shop Manual for my car ($130.00), and worked out a way of bypassing the Passlock II system on my vehicle. After making the modification on my car, I have not had a single instance of No start caused by the Security system.
Last week, as a favor to a friend, I performed the same modification on a 2003 Alero. It took less than an hour. (not counting the time I spent taking photos of my progress) The modification was successful on that vehicle.
Details of the modification are posted on my personal website at:
There are instructions on how to do the modification using two methods. Both methods bypass the security module in the ignition circuit. One bypasses it at the connector to the Body Control Module, which is under the glove box. The other does the bypass near the ignition switch, which can be reached by removing the radio.
The Malibu, Grand Am, and Alero all used the same security system in certain models, and the bypass method works for all of them. Please post back if you find the instructions useful.

I have 2005 and 2006 Malibus, and have no such problem, but I did take a look at your site... Wow, what a treasure!... I've got to explore the stuff there, later -- seems very instructive no matter what model I have...
Thank you for sharing your experience in such a thorough way!

Thanks for the compliment. I doubt if the instructions on my site will help you, as your vehicles have (I think) a newer system, which uses a key with an embedded chip, and is considerably more reliable than the Passlock II system. (My 2007 Cobolt has the new system). You can tell because the keys with the embedded chip have a "+" stamped on them right below the plastic handle. There is, however a way to keep from spending $35.00 per key for replacement keys. When you lose one of your keys, take the other one and go to a hardware store and have two common duplicates made, at $1.50 each. Then take your remaining key with the chip in it, open up the shroud that is around your ignition switch, and tape the transponder key inside the shroud. You will then be able to use ordinary keys to operate your car. The key with the embedded chip needs only to be close enough to the ignition switch so the vehicle can receive it's signal.

I know you posted this a while ago. I have the exact same car and the exact same issues and every time i take it in the car won't do anything so I look like im making it up. Did you ever figure out what was wrong with it?
